Description
Technical field
The present invention relates to the part processing technique field of automobile exhaust gas recirculating system, be specially large mouthful of rounding die of automobile exhaust recirculation cooling system diffuser.
Background technology
Automobile exhaust recirculation cooling system diffuser, its structure is shown in Fig. 1, it includes the large round mouth that an internal diameter is 84mm, diffuser is before carrying out in road welding procedure, this large round mouth is subject to high temperature deformation, and this diffuser is had relatively high expectations to the circularity of this large round mouth in the time of follow-up and cooling system assembling, therefore need this large round mouth to carry out full circle processing.Added man-hour carrying out full circle in the past, and be mostly that the outer wall that is set in round mouth by shaping mould carried out simple full circle, its plastic precision is poor, is only applicable to full circle processing less demanding to circularity and that round mouth is less.
Summary of the invention
For the problems referred to above, the invention provides large mouthful of rounding die of automobile exhaust recirculation cooling system diffuser, it can ensure the required precision of large mouthful full circle.
Its technical scheme is such, it comprises upper die structure and lower die structure, described upper die structure comprises cover plate, described lower die structure comprises base plate, between described base plate and cover plate by rolling guidance set guiding matched moulds, described cover plate bottom is fixed with workpiece briquetting, it is characterized in that: described lower die structure also comprises workpiece locating piece, plug and full circle slide block, described full circle slide block is provided with eight, described eight full circle slide blocks along described plug periphery respectively correspondence be installed on eight slider guides, described slider guide is fixed on slide block base, described workpiece locating piece inner circle is placed on described eight full circle slide blocks combination cylindrical outside, described plug top is through described slide block base, described base plate is fixed in bottom, the combination inner peripheral surface of described plug upper periphery face and described eight full circle slide blocks is the taper seat cooperatively interacting, described slide block base is connected by spring with described base plate.
It is further characterized in that: described slider guide and described full circle slide block radial outside are provided with isometry block, in described isometry block, radial spring are installed; Described full circle slide block and described isometry block top, by slide block cover plate axial restraint, are bolted between described slide block cover plate and described workpiece locating piece.
Adopt mould of the present invention automobile exhaust recirculation cooling system diffuser to be carried out to the shaping of large round mouth, its beneficial effect is: its plastic precision is high, wherein workpiece locating piece is done pushing radially from large round mouth outer wall positions, eight full circle slide blocks are subject to plug effect to large round mouth internal face, thereby completes the full circle processing to large round mouth wall; .
Brief description of the drawings
Fig. 1 is the present invention's automobile exhaust recirculation cooling system diffuser structural representation to be processed;
Fig. 2 is large mouthful of rounding die structural representation of automobile exhaust recirculation cooling system diffuser of the present invention;
Fig. 3 is the plan structure schematic diagram of the lower die structure of large mouthful of rounding die of automobile exhaust recirculation cooling system diffuser of the present invention.
Detailed description of the invention
See Fig. 2 and Fig. 3, the present invention includes upper die structure and lower die structure, upper die structure comprises cover plate 13, lower die structure comprises base plate 2, between base plate 2 and cover plate 13 by rolling guidance set guiding matched moulds 11, cover plate 13 bottoms are fixed with workpiece briquetting 12, lower die structure also comprises workpiece locating piece 10, plug 3 and full circle slide block 8, full circle slide block 8 is provided with eight, eight full circle slide blocks 8 along plug 3 peripheries respectively correspondence be installed on eight slider guides 6, slider guide 6 is fixed on slide block base 5, workpiece locating piece 10 inner circles are placed on the combination cylindrical outside of eight full circle slide blocks 8, plug 3 tops are through slide block base 5, base plate 2 is fixed in bottom, the combination inner peripheral surface of plug 3 upper periphery faces and eight full circle slide blocks 8 is the taper seat cooperatively interacting, slide block base 5 is connected by spring 4 with base plate 2.Slider guide 6 is provided with isometry block 7 with full circle slide block 8 radial outsides, and radial spring 16 is installed in isometry block 7; Full circle slide block 8, is bolted between slide block cover plate 9 and workpiece locating piece 10 by slide block cover plate 9 axial restraints with isometry block 7 tops.In Fig. 1,1 is feet; In Fig. 2,14 is limited post, and 15 is inner guiding post.
Specifically describe below and adopt mould of the present invention to carry out the process of large mouthful of full circle of automobile exhaust recirculation cooling system diffuser: treat that shaping workpiece is positioned over the interior location of die cavity of workpiece locating piece 10, upper die structure and lower die structure under the drive of punch press by rolling guidance set guiding matched moulds, in matched moulds process, upper die structure, slide block base 5 and be fixed on the lower die structure part pressurized on slide block base 5, spring 4 pressurizeds, the top outer conical surface of plug 3 and the combination internal conical surface of eight full circle slide blocks 8 are coordinated to be contacted, eight full circle slide blocks 8 are subject to the effect of plug 3 to do outer moving radially along slider guide 6, together with workpiece locating piece 10, the large round mouth wall of workpiece is carried out to radial compression, complete full circle processing, after full circle completion of processing, punch press unloads the pressure to upper die structure, spring 4, radial spring 16 resiliences, plug 3 is removed the radial compression to eight full circle slide blocks 8, the screen resilience effect that eight full circle slide blocks 8 are subject to radial spring 6 along slider guide 6 do radially in move, thereby remove the constraint to the large round mouth inwall of workpiece, facilitate the taking-up of workpiece.
